Résumé :

Between 1913 and 1940 Karl Escherich wrote Volume 1, 2, 3, and 5 of his textbook and manual « Forest Insects of Central Europe ». Of this classical work, dealing with practical entomology, Volume 4 referring to hemimetabolic insects and the remaining type of butterflies has never been published. Over the years it has become obvious that a revised edition was necessary on this subject, so important to science and practice. But the extent of present knowledge regarding forest pests and the needs of modern forest protection required a completely different approach to the subject. The new work, therefore, is published not as a textbook but purely as a manual, and has contributions from numerous specialists from Germany and abroad. The manual will not only deal with insects but with all other animal genera which are forest pests. For the first time it refers to the whole of Europe. In taxonomical order the following volumes are published at intervals of at least one year: 1. Worms, snails, mites, millepeds, and hemimetabolic insects; 2. Beetles; 3. Butterflies; 4. Otherholo-metabolicinsects; 5. Vertebrates. The second volume deals with the beetles know to have the greatest variety of species among all animal families and at the same time to be most harmful to forestry. This volume includes the Carabidae, Cantharidae, Lymexylonidae, Elateridae, Eucnemidae, Buprestidae, Anobiidae, Lyctidae, Bostrychidae, Meloidae, Serropalpidae, Lagriidae, Tenebrionidae, Lucanidae, Scarabeidae, Cerambycidae, Chrysomelidae, Bruchidae, Curculionidae, Scolytidae, and Platypodidae. Outstanding points of the description are the economically most important families of Lamellicorn-Beetles, Longhorn-Beetles, Weevils, and Bark-Beetles.
